TO WHOM IT MAY CONCERN: The Jacksonville District of the U.S. Army Corps of Engineers (Corps) has received an application for a Department of the Army permit pursuant to Section 404 of the Clean Water Act (33 U.S.C. §1344) and Section 10 of the Rivers and Harbors Act of 1899 (33 U.S.C. §403). The purpose of this public notice is to solicit comments from the public regarding the work described below:
If you are interested in receiving additional project drawings associated with this public notice, please send an e-mail to the project manager by electronic mail at lauren.k.pohlmann@usace.army.mil.
APPLICANT: Walton County Board of County Commissioners
ATTN: Melinda Gates
117 Montgomery Circle
DeFuniak Spring, FL 32435
WATERWAY AND LOCATION: The project would affect aquatic resources associated with Oyster Lake and the Gulf of America. The project site is located south of County Highway 30A; at latitude 30.350801° and longitude -86.247454°; in Santa Rosa Beach, Walton County, Florida.
EXISTING CONDITIONS: Oyster Lake is a coastal dune lake adjacent to the Gulf of America. Oyster Lake has an intermittent connection to the Gulf which sometimes allows the lake to drain to the Gulf in response to higher water levels within Oyster Lake. This natural process reduces the potential for localized flooding around the lake. However, conditions of the beach, surrounding dunes, and lake are not always conducive to draining the lake and, at times, flooding takes place around the lake and impacts the surrounding properties and infrastructure.
PROJECT PURPOSE:
Basic: Flood Control.
Overall: Excavation of the connection between Oyster Lake and the Gulf of America to alleviate flooding of the properties around Oyster Lake in Walton County, Florida.
PROPOSED WORK: The applicant requests authorization to periodically excavate the Oyster Lake outfall . The applicant proposes a trigger point elevation of 4.0 feet relative to North American Vertical Datum (NAVD), which is the elevation of the ordinary high water level of Oyster Lake. The area would be excavated to create a temporary trench that would be approximately 5 feet wide and 2 feet deep. The trench could be as much as 140 feet long or the length necessary to establish connection between the lake and the Gulf depending on beach conditions. Excavated sand would be sidecast on either side of the trench and would erode into the Gulf through natural processes. This would result in the temporary erosion of beach sand into the Gulf. As occurs when the lake naturally drains, the sediment would be redistributed by the tides and the temporary trench would fill back in with sand after excess water within the lake has drained to the Gulf.
AVOIDANCE AND MINIMIZATION: The applicant has provided the following information in support of efforts to avoid and/or minimize impacts to the aquatic environment: “Walton County will only utilize the mechanical opening permit when the beach, dune and lake conditions do not allow Oyster Lake to open naturally. Walton County will coordinate with South Walton Turtle Watch during turtle nesting season to verify that no nests are located within the project area prior to the commencement of any work. All sand excavated for the mechanical opening will be placed adjacent to the trench as the lake flows into the Gulf, the trench will widen and all excavated material will erode into the Gulf. No work is proposed seaward of the MHWL of the Gulf of America.”
COMPENSATORY MITIGATION: The applicant has provided the following explanation why compensatory mitigation should not be required: “Due to the limited impacts associated with the proposed activities, no compensatory mitigation is needed due to the de-minimis nature.”
CULTURAL RESOURCES:
The Corps is evaluating the undertaking for effects to historic properties as required under Section 106 of the National Historic Preservation Act. This public notice serves to inform the public of the proposed undertaking and invites comments including those from local, State, and Federal government Agencies with respect to historic resources. Our final determination relative to historic resource impacts may be subject to additional coordination with the State Historic Preservation Officer, federally recognized tribes and other interested parties.
ENDANGERED SPECIES: The Corps has performed an initial review of the application, the U.S. Fish and Wildlife Service (USFWS) Information for Planning and Consultation (IPaC), National Marine Fisheries Service (NMFS) Section 7 Mapper, and the NMFS Critical Habitat Mapper to determine if any threatened, endangered, proposed, or candidate species, as well as the proposed and final designated critical habitat may occur in the vicinity of the proposed project. Based on this initial review, the Corps has made a preliminary determination that the proposed project may affect species and critical habitat listed below. No other ESA-listed species or critical habitat will be affected by the proposed action.

Pursuant to Section 7 ESA, any required consultation with the Services will be conducted in accordance with 50 CFR part 402.
This notice serves as request to the U.S. Fish and Wildlife Service and National Marine Fisheries Service for any additional information on whether any listed or proposed to be listed endangered or threatened species or critical habitat may be present in the area which would be affected by the proposed activity.
ESSENTIAL FISH HABITAT: Pursuant to the Magnuson-Stevens Fishery Conservation and Management Act 1996, the Corps reviewed the project area, examined information provided by the applicant, and consulted available species information.
This notice initiates the Essential Fish Habitat (EFH) consultation requirements of the Magnuson-Stevens Fishery Conservation and Management Act. Our initial determination is that the proposed action would have s minor adverse impact on EFH and/or fisheries managed by Fishery Management Councils and the National Marine Fisheries Service (NMFS). Implementation of the proposed project would indirectly impact a small area of intertidal primarily sandy substrate. The effects of the project are determined to be minimal and temporary. These habitat(s) are utilized by the following species and their various life stages:

Our final determination relative to project impacts and the need for mitigation measures is subject to review by and coordination with the National Marine Fisheries Service.
NAVIGATION: The proposed structure or activity is not located in the vicinity of a federal navigation channel.
